No disrespect to Michael Phelps, but Sebastian Coe's right. Certainly Phelps is the greatest swimmer in the history of the world. And the most decorated Olympic athlete. He richly deserves and has earned both titles. But greatest Olympic athlete ever? The names of possible contenders for THAT title is mind boggling. How about 2 time decathalon champion Bob Mathias, who won gold when he was 17? Or Al Oerter, four time discus champion? Or Eric Heiden, winner of all five speed skating events at Lake Placid? Or Sonja Heine? Or Pavvo Nurmi? Or Carl Lewis? Or the sainted Jesse Owens? And on and on. Swimmers and gymnasts have an advantage, they have multiple events to contest. Most others compete in only one or perhaps two events. Is Cassius Clay not as great becuse he only won one gold medal?
Michael Phelps is THE towering figure in world and US swimming history. And he is certainly one of a tiny handful of the greatest Olympic athletes of all time. I'm pretty sure he would agree with that, since it is so manifestly true. Putting that question to Lord Coe strikes me as more "gotcha" than anything else.
